Below you can see a picture of a passenger seating half way between upright and flat bed positions.
Of course, the other good thing about flying business class is the food which I found to be very good on this flight. Starting with a preflight drink of Duval Leroy champagne:
Shortly after take-off, cocktail service with a Bloody Mary:
I had the grilled beef tenderloin which was very tender and tasty. I loved the blue cheese sauce and the Lyonnaise potatoes!
I can safely say that this was a very pleasant flight. I really liked Delta's flat-bed seats. Their only drawback is that for the seats which are separated from the aisle by the armrest, it can be a very narrow passage to go through. Otherwise, it is an excellent product providing aisle access to all business class passengers. The long and flat bed seat features a very large armrest. It is way ahead of Air France's current product.
